A kind of pore structure of improving that the present invention proposes improves composite light concrete of intensity and preparation method thereof, and its concrete steps are as follows:
(1) raw material is taken by weight;
(2) load weighted silicate cement, flyash, slag powders, steel-making slag powder, desulfurated plaster, sodium laurylsulfonate, poly carboxylic acid series water reducer, shale pottery, quartz sand, rosin race air entrapment agent, trolamine and water are uniformly mixed 120s in advance to uniform state, then put into load weighted haydites of book structure, mud ceramic granules stirs.
Above step is carried out all at ambient temperature and pressure.
The composite light concrete of gained of the present invention, to carry out mechanical pumping by mechanization transportation or constructs in prefabricated components unit to working-yard.
In the present invention, silicate cement, flyash, slag powders, steel-making slag powder form diversification cementitious material system jointly, thus promote the heat evolution velocity of cement in concrete, comprise four large mineral C in cement
3s, C
2s, C
3a, C
4aF and adjustable solidification agent gypsum, cement from adding water, C before this
3a and adjustable solidification agent gypsum react formation ettringite, prevent C
3the fast hydration of A, makes the aquation of cement can be in " stagnation " state in the long period, after about 2 hours, and C
3s starts a large amount of aquation, forms CSH gel and calcium hydroxide, mutually overlaps, interts, and occurs condensation and sclerosis.Flyash, slag powders, steel-making slag powder are all complementary gelling material, due to containing the more SiO with pozzolanic activity
2, Al
2o
3, SiO
2the Ca (OH) that can be formed with hydrated cementitious
2further combined with formation CSH gel, AlO
3the Ca (OH) that can be formed with hydrated cementitious
2with gypsum remaining in liquid phase further combined with formation ettringite, increase the quantity of hydrated product, closely knit paste structure.And do not participate in the flyash of reaction, slag powders, steel-making slag powder particle will exist as stopping composition, contributes to the intensity improving hardened paste.Because the CaO content in flyash, slag powders, steel-making slag powder is all lower, mix in concrete after there is secondary pozzolanic reaction and significantly can reduce Ca (OH) in slurry liquid phase
2concentration, is unfavorable for the quickening of hydration rate, and the present invention introduces the Ca (OH) that a small amount of white lime comes in supplementary liquid phase especially
2, because its introduction volume is less, be unlikely to the intensity affecting slurry.In the present invention, flyash used selects C class flyash (high-calcium fly ass), but not ordinary fly ash (F class flyash), object is also the Ca (OH) be in increase system
2content, thus the aquation accelerating complementary gelling material.As everyone knows, gypsum and lime are the activity excitants of the complementary gelling material such as flyash, slag powders, steel-making slag powder, and only under these two kinds of exciting agents exist situation simultaneously, this several pozzolanic activity mineral admixture could participate in aquation preferably.The present invention is at introducing portion Ca (OH)
2prerequisite under, by calculate and verify by experiment, introduce the desulfurated plaster of preferred proportion, its main ingredient is dihydrate gypsum (CaSO
4.2H
2o).Dihydrate gypsum in desulfurated plaster is suitable with the dissolution rate of natural dihydrate gypsum, can add water to stir in rear 3d-14d at concrete slowly to dissolve, and dissolves the SO
4 2-constantly three kinds of active mineral admixtures are combined in the present invention, form ettringite, intert in gelling system, contribute to increasing concrete ultimate compression strength and toughness.
Use the present invention effectively can improve the pore structure of haydite concrete, and contribute to improving the concrete mechanical strength of composite light and impermeability, carbonization resistance and anti-Cl
-the weather resistance such as perviousness, have with low cost, green degree is high, reduces the outstanding advantages such as carbon emission.
